Stenotutor crashes when unlocking final words

[qria]

using StenoTutor 0.1.4 on Windows7 64bit

Stenotutor crashes with IndexOutOfBoundException when unlocking final words and (i think) when words exist less than incrementWords.

Notably, beating vowels.les leads to crash when unlocking the final 2 words.
